Elevator emergency rescue basic steps

Elevator trapping incidents have occurred from time to time, such as a shopping mall elevator strike reported by the media. At that time, seven passengers went from the second floor to the second floor, but when the elevator fell to the first floor, it suddenly "strikes" and seven passengers were trapped, including two young children. The rescuers in the mall rushed to the scene after more than 10 minutes of the breakdown. "They use the door to knock the door and use the iron plate to knock the door." From the live video provided by the mall, the rescuers put the two iron plates on the elevator car and then smashed them to the sides. After about 40 minutes, the elevator car door was opened for a person's wide space. The sleepy passenger was rescued.

In some accident reports in the past, we can also see such a situation. Rescuers arrived at the scene and destroyed the elevator doors with cutting equipment to rescue people. Such cases often occur throughout the country.

Elevator emergency rescue is generally only 110, 119 will go to the door to rescue, with a crowbar or rescue tools, directly rescue people. But this is not a professional rescue, but it is also dangerous. Generally, individuals do this relatively little.

Professional elevator rescue is subject to standard requirements, and there are operating procedures, which must be strictly operated in accordance with the regulations. Generally, the power supply is cut off first, and the intercom system of the elevator itself is used to understand the situation of the trapped person and to appease, judge the elevator landing floor, manually crank, warn the trapped person to stay away from the door area, and open the door with the elevator-dedicated triangular key.

Elevator companies and property and maintenance companies will also discuss related issues when they meet. However, there is no unified elevator rescue requirement in China. The coordination of various departments is difficult. It is necessary to cooperate with many parties. The professional rescue problem of elevators is very common but has not been comprehensive. System solution.

If 110 or 119 is in the door of the elevator, the elevator suddenly runs, the safety of the personnel cannot be fully guaranteed. In addition, the damage to the elevator is objectively present, and the replacement parts of the elevator are inevitable. Overhaul problem.

Here, remind the elevator users, once trapped in the elevator, please follow the instructions on the top of the elevator, contact the professional elevator rescue personnel, in the special circumstances to maximize personal safety.
